Fully-covered metal stent removal failure in case of non-malignant biliary strictures: Risk factors and resolution technique.

ABSTRACT:

Background and study aims

Fully-covered-self-expandable-metal-stents (FC-SEMS) are commonly used for non-malignant biliary stricture treatment. Removal failure related to hyperplastic tissue development over the distal margin of the stent has been described but few data are available. FC-SEMS-in-FC-SEMS technique has been described in case reports to overcome FC-SEMS removal failure. Aims of this study were investigating technical success, clinical success, and safety of the FC-SEMS-in-FC-SEMS technique and identification of risk factors for FC-SEMS removal failure in patients with non-malignant distal biliary stricture.

Patients and methods

Endoscopic retrograde cholangiopancreatography (ERCP) procedures performed between January 1, 2020 and May 31, 2023 for FC-SEMS removal
